.TH std::puts 3 "2024.06.10" "http://cppreference.com" "C++ Standard Libary"
.SH NAME
std::puts \- std::puts

.SH Synopsis
   Defined in header <cstdio>
   int puts( const char *str );

   Writes every character from the null-terminated string str and one additional
   newline character '\\n' to the output stream stdout, as if by repeatedly executing
   std::fputc.

   The terminating null character from str is not written.

.SH Parameters

   str - character string to be written

.SH Return value

   On success, returns a non-negative value

   On failure, returns EOF and sets the error indicator (see std::ferror) on stdout.

.SH Notes

   The std::puts function appends the newline character to the output, while std::fputs
   function does not.

   Different implementations return different non-negative numbers: some return the
   last character written, some return the number of characters written (or INT_MAX if
   the string was longer than that), some simply return a non-negative constant.

   A typical cause of failure for std::puts is running out of space on the file system,
   when stdout is redirected to a file.

.SH Example


// Run this code

 #include <cstdio>

 int main()
 {
     int rc = std::puts("Hello World");

     if (rc == EOF)
         std::perror("puts()"); // POSIX requires that errno is set
 }

.SH Output:

 Hello World
